thread_title_generate: {e}

Error message

thread_title_generate: {e}

What it means

Wrapped error from the thread_title_generate agent tool: parsing the args into GenerateConversationThreadTitleRequest (via parse_req) failed, almost always a missing/invalid `thread_id` or `assistant_message` field. The {e} carries the underlying serde/parse detail; the prefix only identifies which tool rejected the call.

Solutions

1. Check the tool call includes `thread_id` (required) as a string
2. Ensure `assistant_message`, if provided, is a string
3. Retry the call with corrected JSON arguments
